What You Get!

A non-competitive, scenic ride of 25, 50, 75 and 100 miles. Well marked and quiet country roads, cue sheets, SAG support, friendly volunteers and our well-stocked rest stops that receive RAVE reviews every year.

PDF Files as well as GPS files through "Ride with GPS"

  • Various GPS files will be available for download for all distances through "Ride with GPS".
  • PDF files will be available for download for all distances.
  • Due to last-minute municipal and state level road construction projects as well as changing traffic patterns we are often unable to finalize the routes until shortly before the ride.
  • We recommend that you use the latest cue sheets from the web site and follow the route markings on the day of the ride.
  • Printed copies of the latest cue sheets will be available during registration.

Starting and Closing Times

All routes open at 6:00am. Century riders should begin no later than 8:00am. All riders must plan to complete their rides by 4:00pm when all routes close and SAG support stops.

SAG Support

Phone equipped SAG's are intended to help riders needing assistance. Priority will be given to riders in emergency situations - illness, injury or irreparable mechanical breakdowns. Flat tires are not considered emergencies. SAG service stops at 4:00pm
